Alicia walks 4 miles in 1 hour and can speed walk 5 miles in 1 hour. What percent of Alicia's average speed walking rate is her
RSB [31]

Answer:

The % Alicia speed walking is 125 % of average walking

Step-by-step explanation:

Given as :

Distance cover by Alicia while walking = 4 miles

Time taken                                               = 1 hour

So, Speed of Alicia while walking = \frac{Distance}{Time}

Or,                                            S 1  =  \frac{4 miles}{1 hour}

I.e                                              S 1  =  4 mph

And

Distance cover by Alicia while speed walk  = 5 miles

Time Taken                                                      = 1 hour

So, Speed of Alicia while speed walking = \frac{Distance}{Time}

Or,                                            S 2  =  \frac{5 miles}{1 hour}

I.e                                              S 2  =  5 mph

Or,   % Rate = \frac{5}{4} ×100 = 125

Hence The % Alicia speed walking is 125 % of average walking  Answer
